BenzigarPeter has added functionality to a previously published tip. The original, submitted by Murray Clack some 15 years ago, allowed users to detach an xref by selecting the object in an AutoCAD drawing. Benzigar has added the ability to do other things with a selected xref, including open, bind, and unload. To use this routine, load the LISP file and type in the command DetXrf. You will be prompted first for an action, and then to select an xref. This tip is a good example of using small functions and calling those functions depending on the choices of the user. Thanks, Benzigar.
